Last Day is no longer being developed or supported by its developers and translators. These two, newer mods offer a similar and better experience:
S.T.A.L.K.E.R.: Last Day is a S.T.A.L.K.E.R. mod pack based on Call of Misery and version 1.4.22 of Call of Chernobyl, originally created by the Eastern S.T.A.L.K.E.R. community. It includes several addons previously unknown to the majority of the western S.T.A.L.K.E.R. community, such as MLR, which adds a lot of new characters and tasks, Outfit Marauder, adding lootable outfits on fallen stalkers, or an extended edition of Outfit Addon, adding not only outfits and helmets already present in the regular version of Outfit Addon, but also several variants of all types of apparel: regular, worn, and damaged.
Below is a flowchart detailing various projects from which Last Day derives. It is recommended to experience these first.

Fairly simple. These files need to be installed into a single directory, in order.
The mod runs standalone, meaning it should be installed on its own without being combined with Call of Chernobyl or Call of Misery.
An older version of Last Day is available here:
Here is a full list of addons and features included in Last Day:
Additionally, there are new models for NPCs and mutants, new artifacts, new mutant parts, new consumables, a simulated PDA network, stash descriptions (like in Shadow of Chernobyl), new icons, new music, new radio tracks, changes in prices, PDA tabs from Call of Chernobyl 1.5 (relations, encyclopedia etc.), and more.
Mikhail Grishin, the main developer of Last Day, announced today that development on Last Day has ceased.
This might not come as a surprise to many of you. Updates to both Last Day and its translation have been few, and Last Day Lite—another project released by the Last Day team, based on Dead Air—was never translated or even announced here. In addition, my own communication with Grishin has been sparse, and my general activity in the S.T.A.L.K.E.R. community has dwindled.
Perhaps, one day, there will be a return to the Last Day translation to finish things up on our part. Nevertheless, Last Day will remain on Mod DB unless we ever get a request from its creators to take it down, and we have a repository on GitHub for the Last Day translation—a repository that anyone can contribute to at any time.
Outside of Last Day, my team and I are working on a translation for another mod, the progress of which can be seen on our group page.
Some information about a new mod on the scene from our partners in modding.
A few words from SashaRed, the leader of the translation team for Last Day.

I do not own anything, found this addon on another website. Factions no longer change their attitude towards each other so fast and easily, compared to...
WARNING: MIGHT BE UNSTABLE ON SOME MACHINES. Make backup of your current "gamedata" folder or use JSGME. Playing on DX9 and/or above is highly recommended...
I've been getting Crashes To Desktop anytime I complete jobs from NPC's that require to find a PDA in a stash and return it to them. Whenever I click "1. The Job is done" in the chat window it just crashes. I did a fresh install of the mods and made sure no other mods were interfering and it still kept happening.

It looks to be when completing the quest the increased rep to the NPC just causes an error, this mission has been the only one I've done so far though.
Yeah. That's been fixed in the latest translation patch. Moddb.com
Ok thank you, will download those and retry :)
Edit: That worked, thank you Sasha :)
Woo. No problem.
Sorry if this is the wrong place to post this, and sorry if this isn't enough information but I keep on getting a CTD when I try to enter the Wild Territory. I've been in there several times before without a problem in this save-game. This is what I guess is the relevant part of the log?

I don't know what's up. Might've messed up some script.
Great merge. It seems that the dynamo is not activated because of a missing line in weapons.ltx
Also, the spawn is pretty ****** at the flea market xD even at 0.25
Do you mean the handcrank generator? I'd love to know how to find that thing, can't see it anywhere.
Dynamo?
And yeah, guess it really is a market now.
Hi, is there any way to further tweak the population factors for mutants/humans? I have set both to 0.25 in options but the maps still feel crowded as hell.. boars charging me every minute is getting kinda annoying. Thanks in advance!
Did you change those on ongoing playthrough? If so, it might actually be better idea to just start a new game because npc's and mutants won't just despawn, then have to die, however after the change all new npc's and mutants will be at 0.25.
Not sure. Maybe the developers have intended this.
